| Mower has plenty of torque, can mow my hilly 1/2 acre lot for about 1.5 hours in 2nd gear. Takes only about 48 hours to charge at 4 Amps. Built special battery rack on rear to distribute weight of the batteries equally between front and rear. This rear weight helps traction of rear tires on hills. The battery weight in front helps minimize " popping wheelies". Rear Battery Rack is High enough to allow towing of carts etc as before. WebPage | |
